The same precision verification testing has been tested for zesty- proposed with the same result as X and Y :
[Verificaton zesty] # i386 - Significant performance increase using the zesty-proposed/i386 package inside a 32-bit LXD container build using a Ryzen CPU with Intel SHA Extension capability. - Same performance (as expected) using the zesty-proposed/i386 package on a non SHA Extension Intel CPU (i7-6770HQ) with zesty-proposed package. # amd64 - Significant performance increase using the zesty-proposed/amd64 package on Ryzen CPU with Intel SHA Extension capability. - Same performance (as expected) using the zesty-proposed/amd64 package on a non SHA Extension Intel CPU (i7-6770HQ) with zesty-proposed package. Note : I unfortunately don't (nor colleagues) have access to a Intel CPU with SHA Extension capability at our disposal. Ideally, if someone has access to one to test it would be good. Otherwise, I think it is safe to rely on upstream author of the patch who confirmed it was working as expected using a Intel CPU with SHA extension capability. Reference : https://github.com/openssl/openssl/issues/2848 "...Myself I tested on Intel processors, yes, with/without...." Additionally, we also had some feedbacks from Justin Erenkrantz, a affected users using a Ryzen/Naple CPU.
